Depends on the mainboard thats in it ...
what that dino is ... its a 486
now the amd k-6 (486) cpu came in mhz sizes from 66 , 100,133,166,200 ,233,266,300,350,400,450,500, and ended at 550mhz
look inside and get the mb number /manufacturer off of it and we can go from there .
if its upgradable to the higher cpu's its a Dance of the jumpers kinda thing to get it to work .. ( the last of the 486 line has a few Bios controlled settings for clocking ,,,, but most of them ive seen and played with are jumpers)
some of the cpu's/mb's do overclock/ accept a higher cpu,,,and there's others wount budge nomatter what ya do to them ...
I've got several k-6 cpu's laying around ... ranging from 166 up thru the 450's and i may even have a spare 500,550 . ive got several compleat pc's yet of this vintage and id have to go check what they've got too ,,mostly gateway stuff (they had higher end hardware in them normally ,,,asus mb's ,monster cards , and so forth)
so if its an upgradeable MB ... i'll give ya a cpu if i have one thats compatable .
